HOSE CONSTRUCTION.

, Specicatonof Letters Patent.

Application filed 'March 5, 1913. Serial No. 751,992

To all l1J/wm, fit may concern:

Be it known that I, GHARLES'K. HUTH- siNG, a citizen vof the UnitedStates of America, residin in the cityof St. Louis .and State of.M1ssouri, have invented certain new and useful Improvements in HoseConstruction, of which the following is a specification.

The primary object of this invention is to provide improved means inhose construction, such as fire hose, whereby the creasing of the hose',when reeled or when short bends are made therein when flattened, is notdetrimental to the inner lining or tubing thereof. n

Another object is to provide improved means whereby the hose 1s mademore pliable for reeling. i

A further object is to provide means for relieving the weight from thecreased portions of the inner lining or tube of a hose, which weight isbrought about byreason of the hose being laid upon itself when not inuse.`

A still further object is to provide an improved ire hose of4k suchconstruction that the inner tube or lining can be more easilyl insertedand drawn into the outer lining.

' `Other and further objects will'appear in the specification, and bespecifically' pointed out in the appended claims, reference being had tothe accompanying drawings exemplifying the invention, and in which,

F1 re 1 is a transverse section through a `lire ose, showingthisimproved construe tion applied thereto. Fig. 2/is a transverse sectionof this improved fire hose when fiattened. Fig. 3 is a perspectiveview,'slight|ly reduced. in size, of a portion of one end oi a length ofthe inner lining,y or tube of lire hose, showing this improvement.Figjfi, is a horizontal section, showing two 'sections of hose cou-pledtogether.

- Referring to the drawings: the inner tube or lining of a fire hase,which is preferably made of rubber. Secured thereto, outside thereof,and on opposite sides, are a pair of filling strips 2,said strips beingof such widththat they will not meet at their adjacent vside edges 3,thus forming a pair of longitudinal recesses 4, said recesses beingdiametrically opposed to each 1 designates other. Mounted on the outsideof the inner lining 1 and the filling strips 2 isthe outer lining orcasing 5.

In hose of any size, such as fire hose, when said hose is no't in use itwill collapse, proyiding there is not enough reinforcing to sustain thehose in its circular formation. But in the majority of instances, hose'of this type, being flexible, is of a collapsible formation so it can bereadilyreeled when not in use. When the crease lines are once formed byflattening, these'crease lines will always be followed whenever the hoseis collapsed. For this reason the bends of the hose forming the creasesare so abruptV that friction iscaused in the material of the hoseadjacent the bends, especially in the inner rubber lining or tube, sothat the adhesion s lrokemand in a short while the hose will ea r.

Referring to Fig. 2, which shows the hose in-a flattened condition,creases 6 are formed adjacent the longitudinal recesses 4. And bends 7will be formed on the inner linino 1 in the .recesses 4. But by reasonof the filling strips 2, the weight that might be applied to the hosewhen in its Hattened con(l dition will be sustained by said fillingstrips', the bends 7 of the inner lining 1 being protected in therecesses 4. As no pressure is brought to bear on said bends 7 said bendswill assume more of a natural curve. Therefore, said bends will not besubjected to the Patenten .any ai, 1914.

vrla

abrupt bending friction as they lwould beif they were squeezed together.y

In order to provide a good coupling connecti on when lengths of hose arecoupled together, it is preferable to have the strips 2 adjoin eachother adjacent the ends of the length, as shown at 8 in Figs. 3 and 4.So that when lengths of hiise are coupled together, there will be asolid foundation of fabric entirely around the hose so that a solidjoint will be formed.

It is readily seen how new inner linings of this imprsved constructioncan be readily inserted into old outer casings. And, furthermore, thisimproved construction of inner lining can be more readily drawn into anoutercasing by reason of the filling strips having ia space formedbetween their side ed frcs, and acertain amount of looseness will Ont beformed when dravrving the-inner lining l* into the outer casing.

By having the filling 4strips 2 merged together adjacent the ends ofeach length of inner tube' 1, said strips, of course, being` gu'mmed tosaid inner tube, when length of hose are coupledtogether and water pressure is maintained in the hose, the portions 8 .of the filling strips 2,being gummed to .the inner tube 1, -will preventwthefwater from gettingin between the inner tube 1 and said portions 8. These iillin strips 2,when applied to the outside oft e rubber 'inner tube 1, serve asreinforcements or vlli stifeners to theiiiner tube, as, when the innertube is being mounted in the outer lining, it being pulled in,considerable Vstrain is 'given to the 'inner tuber'T-liese strips,therefore, relieve the strain on the'inner tube. This improvedconstruction `of inner tube provides for the tube being'expansible, theportion of the tube adjacent the'recesses or spaces 4 expanding againstthe outer lining 5 when pressure is applied to the hose.
